@Olivecatto That they were looking to find a single person with multiple qualities that rarely happen in a single being.
So, basically, it probably means they've hired you to do the work of 3 or more people, and pay one salary.
Sorry. I'm very cynical.
@Olivecatto I don't really think everything is as bad as the worst-case scenarios I sometimes come up with, but I do think it can be self-protective to remember that sometimes workplaces ... aren't open and honest about challenges present in the office.
Most likely, what they really meant was that you have several talents they did not expect in a single candidate.
